Question

I need to replicate this XML in C# and Linq to XML. I dont want any dependencies to other libraries other than the normal .NET ones. The XML is shown below.

Problem: I can’t figure out how to print these two lines:

<?mso-application progid="Excel.Sheet"?>
<Data ss:Type="String">name</Data>

Full XML document:

<?xml version="1.0" encoding="utf-8" ?>
<?mso-application progid="Excel.Sheet"?>
<Workbook xmlns="urn:schemas-microsoft-com:office:spreadsheet"
  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xmlns:x="urn:schemas-microsoft-com:office:excel"
  xmlns:x2="http://schemas.microsoft.com/office/excel/2003/xml"
  xmlns:ss="urn:schemas-microsoft-com:office:spreadsheet"
  xmlns:o="urn:schemas-microsoft-com:office:office"
  xmlns:html="http://www.w3.org/TR/REC-html40"
  xmlns:c="urn:schemas-microsoft-com:office:component:spreadsheet">
    <OfficeDocumentSettings xmlns="urn:schemas-microsoft-com:office:office"></OfficeDocumentSettings>
    <ExcelWorkbook xmlns="urn:schemas-microsoft-com:office:excel"></ExcelWorkbook>
    <Worksheet ss:Name="Sheet 1">
        <Table>
            <Row>
                <Cell>
                    <Data ss:Type="String">name</Data>
                    </Cell>
                                <Cell>
                    <Data ss:Type="String">status</Data>
                </Cell>
                           </Row>
            <Row>
                <Cell>
                    <Data ss:Type="String">Niike2</Data>
                </Cell>
                <Cell>
                    <Data ss:Type="String">Enabled</Data>
                </Cell>
            </Row>
        </Table>
    </Worksheet>
</Workbook>

Code:

XNamespace ns = "urn:schemas-microsoft-com:office:spreadsheet";
XDocument doc = new XDocument(
    new XDeclaration("1.0", "UTF-8", string.Empty),
        new XComment(String.Format("Exported: {0}", DateTime.Now)),
        new XElement(ns + "Workbook",
            new XAttribute(XNamespace.Xmlns + "xsi", "http://www.w3.org/2001/XMLSchema-instance"),
            new XAttribute(XNamespace.Xmlns + "x", "urn:schemas-microsoft-com:office:excel"),
            new XAttribute(XNamespace.Xmlns + "x2", "http://schemas.microsoft.com/office/excel/2003/xml"),
            new XAttribute(XNamespace.Xmlns + "o", "urn:schemas-microsoft-com:office:office"),
            new XAttribute(XNamespace.Xmlns + "html", "http://www.w3.org/TR/REC-html40"),
            new XAttribute(XNamespace.Xmlns + "c", "urn:schemas-microsoft-com:office:component:spreadsheet"),
            new XElement(ns + "Worksheet",
            new XElement(ns + "Table",
                new XElement(ns + "Row",
                    new XElement(ns + "Cell", "name")
                    )
                )
            )
        );

The second line with <? …. ?> is called a Processing Instruction. The rest is just manipulating namespaces.

XNamespace ss = "urn:schemas-microsoft-com:office:spreadsheet";
XNamespace xsi = "http://www.w3.org/2001/XMLSchema-instance";
XNamespace x = "urn:schemas-microsoft-com:office:excel";
XNamespace x2 = "http://schemas.microsoft.com/office/excel/2003/xml";
XNamespace o = "urn:schemas-microsoft-com:office:office";
XNamespace html = "http://www.w3.org/TR/REC-html40";
XNamespace c = "urn:schemas-microsoft-com:office:component:spreadsheet";

XDocument doc = new XDocument(
        new XDeclaration("1.0", "UTF-8", string.Empty),
        new XComment(String.Format("Exported: {0}", DateTime.Now)),
        new XProcessingInstruction("mso-application", "progid=\"Excel.Sheet\""),        
        new XElement("Workbook",            
            new XAttribute(XNamespace.Xmlns + "xsi", "http://www.w3.org/2001/XMLSchema-instance"),
            new XAttribute(XNamespace.Xmlns + "x", "urn:schemas-microsoft-com:office:excel"),
            new XAttribute(XNamespace.Xmlns + "x2", "http://schemas.microsoft.com/office/excel/2003/xml"),
            new XAttribute(XNamespace.Xmlns + "ss", "urn:schemas-microsoft-com:office:spreadsheet"),
            new XAttribute(XNamespace.Xmlns + "o", "urn:schemas-microsoft-com:office:office"),
            new XAttribute(XNamespace.Xmlns + "html", "http://www.w3.org/TR/REC-html40"),
            new XAttribute(XNamespace.Xmlns + "c", "urn:schemas-microsoft-com:office:component:spreadsheet"),
            new XElement("Worksheet", new XAttribute(ss + "Name", "Sheet 1"),               
                new XElement("Table",
                    new XElement("Row",
                        new XElement("Cell",
                            new XElement("Data", new XAttribute(ss + "Type", "String"),"status"))
                    )
                )
            )
        )
    );
